A tradition for excellence going back nearly 400 years has earned a West Lindsey grammar school a place in the national school 'charts'.
Caistor Grammar School has been awarded a place in the 2013 Good Schools Guide.
It follows an inspection at the Church Street campus just before Christmas.
The school, which has 651 children on its roll, is praised in the GSG for its leadership, academic achievement and for the students' attitude to learning.
Inspector Elizabeth Coatman said the school was: "A very strong contender if you are after sound academic values and achievement, with firm discipline allied to encouragement of talent and individuality – plus a good dollop of heart.
"Roger Hale, who has been head since 1996, is an ex-Ofsted inspector who sits on various local and national committees including the Association of School and College Leaders, the Education Funding Agency and the Grammar School Heads' Association.
"He's very energetic, talks at a rate, is friendly, humorous and tremendously enthusiastic about the school.
"Mr Hale knows all the pupils, by whom he is liked and respected, and is a lover of tradition.
"Staff have a passion for helping pupils to do the best they can, endorsed by all the pupils we met.
"Their termly assessments for effort and achievement are the longest comments I have ever seen on student reports."
Mr Hale said the Good Schools Guide inclusion was emphasised by last week's confirmation that Caistor Grammar had achieved a 100 per cent GCSE five A to C return for the fourth successive year.
"And the recent bad weather emphasised how much time and effort we put in to keeping our school open," he said.
"Because Caistor can be very difficult to reach in winter and we have 39 different feeder schools in many outlying communities, we run a system called Snow Bored.
"It means all our classes set work for children to do at home if they can't get in. We only had to close for the one day earlier this month."
Head girl Sophie Manson, 17, described the Caistor Grammar ethos as family-orientated.
"It's a small community where everyone gets on really well," she said
The sixth form is really involved with helping pupils in the lower school.
Deputy head girl Ava Hodson, 18, said: "Everyone knows each other and because teachers know students personally they can pinpoint their strengths – and weaknesses."
Head boy Oliver Fairclough, 18, said: "It's really satisfying to know that all the teachers are really passionate about their subjects."
